Harry Pothead?

A teenage cast member of the "Harry Potter" movies has appeared in a London court and admitted to growing marijuana.

Jamie Waylett pleaded guilty to growing the drug during a hearing Thursday at City of Westminster Magistrates' Court. The 19-year-old Waylett plays school bully Vincent Crabbe in all six installments of the film franchise.

Police found eight bags of cannabis and a knife during a search of a car Waylett was riding in. They then searched his mother's house and found 10 marijuana plants.
